I'd be nice if the default flag weights found in "admin/structure/flags/manage/foo_flag" could be exported using Strongarm/Features. That way administrators don't have to migrate changes from local to DEV -> QA -> Prod.

Technical background

Currently _flag_weights_get_default_weight() gets the default flag weight from the database using:

function _flag_weights_get_default_weight($fid) {
  return (int) db_query("SELECT default_weight FROM {flags} WHERE fid = :fid", array(':fid' => $fid))->fetchField();
}

This is used by the flag_weights_form_flag_form_alter() hook_form_FORMID_alter implementation to retrieve the default flag weight in flag_weights.module.
